Soil.spec package specific environmental variables

Description

Generates internal environment / package specific parameters and settings that can be later on passed to other functions.

Usage

spec.env(MIR = c(390, 7500), NIRS = c(3900, 12500), 
   NIRP = c(4000,10000), VISNIR1 = c(420, 960), 
   VISNIR2 = c(1020, 1770), 
   VISNIR3 = c(1830, 2480),
   icraf.htsxt = c(3578, 7497.964, 599.76), 
   icraf.alpha = c(2542, 3998.12872, 399.387991), 
   icraf.mpa = c(2307, 12493.2, 3598.69),  
   CO2.band = c(2350.8,2379.8), signif.digit = 5, 
   attributes = c("ORCCNS", "PHIHOX", "ALUM3S", 
   "ECAM3S", "EXKM3S", "EMGM3S", "ENAM3S", "EXB", 
   "NITCNS", "SNDLDF"), 
   mdnames = c("MID", "Instrument_name", "Instrument_URL", 
   "Laboratory_name", "Laboratory_contact", "Laboratory_URL",
   "Material_class", "Wavenumber_conversion", "Wavenlength_unit",
   "Location_error"), show.env = FALSE)

Arguments

`MIR`	`"numeric"`, mid-infrared part of spectra
`NIRS`	`"numeric"`, near infrared part of spectra
`NIRP`	`"numeric"`, near infrared part of spectra
`VISNIR1`	`"numeric"`, visible near infrared part of spectra
`VISNIR2`	`"numeric"`, visible near infrared part of spectra
`VISNIR3`	`"numeric"`, visible near infrared part of spectra
`icraf.htsxt`	`"numeric"`, ICRAF MIR part of spectra
`icraf.alpha`	`"numeric"`, ICRAF alpha-MIR part of spectra
`icraf.mpa`	`"numeric"`, ICRAF VISNIR part of spectra
`CO2.band`	`"numeric"`, wavenumbers for the CO2 band
`signif.digit`	`"integer"`, default rounding system for absorbances
`attributes`	`"character"`, standard target variables of interest: `"ORCCNS"` (Organic carbon content in soil estimated using the CNS elemental analyzer), `"PHIHOX"` (soil pH measured in water), `"ALUM3S"` (Aluminium concentration estimated using the Mehlich 3 solution), `"ECAM3S"` (exchangeable Calcium determined using using the Mehlich 3 solution), `"EXKM3S"` (exchangeable Potassium determined using using the Mehlich 3 solution), `"EMGM3S"` (exchangeable Magnesium determined using using the Mehlich 3 solution), `"ENAM3S"` (exchangeable Sodium determined using using the Mehlich 3 solution), `"EXB"` (sum of exchangeable bases), `"NITCNS"` (total nitrogen estimated using estimated using the CNS elemental analyzer), `"SNDLDF"` (weight percentage of particles 50-2 mm size determined using the laser diffraction method)
`mdnames`	`"character"`, standard metadata names
`show.env`	`"logical"`, specifies whether the output environment should be printed
